Blue-headed/Cassin's Vireo Pueblo Co. 4/18

[Brandon K. Percival]

Jeannie Mitchell photographed a Vireo at the Headquarters at Chico Basin Ranch (fee area), Pueblo County today.  Tony Leukering has seen the photos, and thinks it is likely a Blue-headed.  A few others seem to be leaning toward Blue-headed too.  Spring time Cassin's and Blue-headed Vireos seem to be a very tricky identification sometimes.

Good birding,
